Calculation of multivariate normal probabilities by simulation, with applications to maximum simulated likelihood estimation

We discuss methods for calculating multivariate normal probabilities by simulation and two new Stata programs for this purpose: -mdraws- for deriving draws from the standard uniform density using either Halton or pseudo-random sequences, and an egen function -mvnp()- for calculating the probabilities themselves. Several illustrations show how the programs may be used for maximum simulated likelihood estimation. -- simulation estimation ; maximum simulated likelihood ; multivariate probit ; Halton sequences ; pseudo-random sequences ; multivariate normal ; GHK simulator
